Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer detection, in particular to a soil fertilizer chlorine content detection device. Background Art

[0002] Soil fertilizers are an important component of agricultural production, playing a vital role in improving soil fertility and promoting plant growth. During the production process, the chloride content in fertilizers needs to be measured. Currently, the Mohr method is commonly used. This method is an argentometric method in which chloride ions react with silver ions to form a silver chloride precipitate. An indicator (such as potassium chromate) is used to indicate the endpoint of the titration. Once the chloride ions in the solution are completely precipitated, the excess silver ions react with the indicator, causing a color change (e.g., from pale yellow to brick red), thus determining the endpoint. The Mohr method involves the following steps: 1. Sample preparation: Weigh a certain amount of fertilizer sample, dissolve it, and filter it to obtain the test solution. 2. Indicator addition: Add potassium chromate to the test solution. 3. Titration: Titrate with a standard silver nitrate solution until the solution changes color. 4. Calculation: Calculate the chloride ion content based on the volume and concentration of silver nitrate consumed. This method requires repeated testing and averaging, making it relatively cumbersome. Therefore, we have developed a device for measuring the chloride content in soil fertilizers to address this issue. Utility Model Content
